Man turns up at his wife's memorial and makes a speech in which he accuses her of selfishness in committing suicide.
Man (same man, let's call him Our Man for brevity), a surgeon, hooks up with a dodgy cockney (we'll call him Lee, because that's his name), who is an eco-eccentric and survivalist with a whole suite of 'rooms' deep underground beneath Temple [remember that, you'll need it later] tube station. They run a business providing medical services to those who are unwilling to go through the usual medical channels. Patching up gunshot wounds, for instance.
We discover that Our Man's wife isn't actually dead. She is in a 'hospital ward' in the underground complex, next to a laboratory in which he is continuing her research into a possible cure for her illness.
Lee brings in a mate (we'll call him Jamie) with a gunshot wound. Jamie arrives with £2 million in a brown paper bag (actually a sports bag). He ran away with the cash from a robbery, leaving his fellow robbers at the mercy of the police. Who are now looking for him. The robbers that is. And the police of course.
Jamie needs a blood transfusion but they have run out of the universal O negative. Our Man phones the only person he knows with that blood type - Anna, his wife's co-researcher and his ex lover - and 'invites' her to see his new home, where she is knocked out with chloroform and her blood used on Jamie.
Anna finds Our Man's wife and agrees to help the research.
Jamie's pregnant wife is given a 'burner' phone with which to communicate with Jamie - the underground complex has full WiFi, obviously - and not surprisingly she gets interrogated. By the police. And the mates of the by now incarcerated robbers.
Our Man discovers that his wife is suffering renal failure and needs a kidney transplant. He makes contact with an underworld supplier of kidneys and needs £100,000 to buy one. So he steals the money from Jamie's stash.
Sounds a promising plot for a TV show? It. Does. Not. Unless it's a comedy. Which Sky's Temple is not, being presented as a 'medical crime drama'.
I've watched some dross in my time as an armchair TV critic but this takes the proverbial biscuit. Want a recommendation? Avoid it like the plague. The above summary covers five episodes of this ludicrous show. There are many more but I won't be watching.
